Which artery is primarily used for blood pressure measurement?

1. Femoral artery

2. Radial artery

3. Carotid artery

4. Brachial artery

The correct answer is: Brachial artery

The brachial artery is the primary artery used for blood pressure measurement because it is located within the arm, making it easily accessible for healthcare providers. It is positioned at a depth that allows for accurate placement of the sphygmomanometer cuff, which is essential for obtaining precise blood pressure readings. The brachial artery's size and location in relation to major arteries also help in capturing the true pressure exerted by circulating blood in the body. Using this artery allows for a standardized approach to measuring blood pressure, which is crucial for monitoring cardiovascular health. The other arteries listed may be used in different clinical settings or for specific patient assessments but are not the standard for routine blood pressure measurement.
